Poliomyelitis is a highly contagious viral and infectious disease that affects the central nervous system causing permanent paralysis and even death, mainly in children between five and ten years old.
Before the triumph of the Revolution, Cuba registered an average rate of 300 cases annually, but in 1962, the government of Cuba began massive annual campaigns. To this day more than 79 million doses of this vaccine have been applied; therefore the Cuban population under 62 years of age is fully protected against this disease.
